Garbled Communication Alarm

[Squire66]

I am receiving an error message "Garbled communication response from Modbus secondary(7): Response..." I have several plcs communicating to one plc via radios, and Lookout is talking only to the one plc. What does this message mean? Is the problem between the plc and the computer, or could it be between the plcs?

Have you tried increasing the Receive gap under Options>>Serial Port Settings?  The alarm is very likely about Lookout's communication (or lack thereof) with the PLC it's connected to.

I do not just want to increase the Receive Gap. This problem does not occur on a regular basis, but when it does it happens repeatedly. I am hoping to identify the problem before setting the alarm timer higher to avoid the alarms.

Hi Squire66,

What version of Lookout are you using? Do you still receive errors if you increase the Receive Gap?

Have a great day!
